<br>
Thank you for your answer.<br>
So If I understand it, you can't use "periodic" boundary conditions in <br>
the angular direction (y), is that right?<br>
<br>
I tried the "SodSpherical" as suggest, using the<br>
<br>
By the way I test, the "SodSpherical" setup command written in the flash <br>
documentation:<br>
"./setup SodSpherical -auto -2d -geometry=spherical"<br>
<br>
While the simulation can be initialized normally, it does not give any <br>
results:<br>
The first checkpoint (sod_sph_hdf5_chk_0000) contains the expected data, <br>
but starting from the second one (0001) the data are all wrong, or more <br>
precisely they don't exist anymore ("dens" is -none- everywhere).<br>
<br>
I'm currently using FLASH4.6.2. I suppose something is wrong with either <br>
my installation of FLASH or with this version of FLASH.<br>
Could someone try the "SodSpherical" problem and tell me if they obtain <br>
the same results.<br>
<br>
Best regards,<br>
